Turner syndrome, 45 X, is a genetic disorder of human females. It is usually caused by the loss of one of the X chromosomes.

Turner's syndrome occurs in 1 out of 2000,[1] to 1 out of 5000 female births.[2] The condition is much more common in utero (that is, before birth). About 1–2% of all conceptions are affected, of which only 1% survive to birth.[1]

Girls with Turner syndrome often have webbed necks, short stature, broad chests and low hairlines. Other health problems may be present, such as heart disease, hypothyroidism (reduced hormone secretion by the thyroid), vision problems, and diabetes. There may be autoimmune diseases.[3]
